“…With time, the fungus could get acclimatize to the changes occurred by PGT in the medium and showed enhanced mycelial growth which confirmed that the organism was able utilize PGT as their carbon and energy source. Talaromyces sp., Penicillium citrinum H7 and Aspergillus nidulans VKPM F-1069 also effectively showed increased biomass growth when inoculated in PGT spiked medium as mentioned in earlier researches (Savinova et al, 2019;Dos Santos et al, 2022).…”

“…Considering the application of fungal strains in removal of PGT, the best claimed result till date was achieved by using Penicillium citrinum H7 which could remove around 90% of PGT (Dos Santos et al, 2022). The particular strain in this study, Aspergillus niger NAAC, thus, can be claimed as a more efficient agent for removal of the PGT from surrounding environment when compared with the previous published reports.…”

“…In recent days, Talaromyces sp. and Penicillium citrinum H7 were also reported to be able to degrade progesterone (Dos Santos et al, 2022). However, even though these microbes were claimed for effective biodegradation, no studies included the management strategy of these effective microbial strain.…”

The presence of hormones, drugs and chemicals in the environment are disrupting the ecosystem. The existence of chemicals in the environment is a threat to the ecosystem as they have dangerous effects on animals, plants and microbes. Progesterones are steroid hormones used for human contraceptives and therapeutic purposes as well as promoting animal growth. The cases of consumption of progesterone for medical purposes are much higher than estrogens, however, much studies related to estrogens have been conducted thereby neglecting the effects of progesterone. This invention focuses on removal of progesterone using fungal strain. Aspergillus niger NAAC efficiently degraded the progesterone content and transformed it into non-toxic end product. The uniqueness of this study involves preparation of a formulated product which would store the fungal strain and maintain its viability. The bioformulation was prepared using used vegetable cooking oil mixed with water as carrier. The bioformulation would reduce the efforts required to isolate the microorganism for regular usage and can be commercialized for large scale applications. To determine the storage conditions of bioformulation, various parameters were analysed which showed that storing the formulation in air tight container at room temperature would result in maximum longevity of the efficient strain.

“…Our research group has previously studied different fungi strains' capabilities in transforming compounds (Silva Conceição et al 2021; Pereira dos Santos et al 2022). A wide variety of microorganisms are helpful in biocatalysis as they can transform several chemicals, providing many catalysts in small volumes and high turnover rates of enzymes and cofactors (Wu et al 2021).…”

The current industrial and human activities scenario has accelerated the widespread use of endocrinedisrupting compounds (EDCs), which can be found in everyday products, including plastic containers, bottles, toys, cosmetics, etc., but can pose a severe risk to human health and the environment. In this regard, fungal bioremediation appears as a green and cost-effective approach to removing pollutants from water resources. Besides, immobilizing fungal cells onto nano brous membranes appears as an innovative strategy to improve remediation performance by allowing the adsorption and degradation to occur simultaneously. Herein, we developed a novel nanostructured bioremediation platform based on polyacrylonitrile nano brous membrane (PAN NFM) as supporting material for immobilizing an endophytic fungus to remove bisphenol A (BPA), a typical EDC. The endophytic strain was isolated from Handroanthus impetiginosus leaves and identi ed as Phanerochaete sp. H2 by molecular methods. The successful assembly of fungus onto the PAN NFM surface was con rmed by scanning electron microscopy (SEM). Compared with free fungus cells, the PAN@H2 NFM displayed a high BPA removal e ciency (above 85%) at an initial concentration of 5 ppm, suggesting synergistic removal by simultaneous adsorption and biotransformation. Moreover, the biotransformation pathway was investigated, and the chemical structures of fungal metabolites of BPA were identi ed by ultra-high performance liquid chromatography -high-resolution mass (UHPLC-HRMS) analysis. In general, our results suggest that by combining the advantages of enzymatic activity and nano brous structure, the novel platform has the potential to be applied in the bioremediation of varied EDCs or even other pollutants found in water resources.
